Plants cannot move like animals, but they communicate and respond to the environment through their own movement—a kind of “plant body language”. Scientists have been surprised by these movements and created inventions based on them.
Everyone knows sunflowers turn to face the sun as it moves across the sky. This gave engineers the idea to create SmartFlower solar panels(电池板). They are in the shape of flowers, and each “petal”(花瓣) is a solar panel. SmartFlower follows the sun all day, which helps produce 40% more energy than normal solar panels. After dark or when there’s bad weather like heavy rain, the “petals” will close up.
Some plants, such as ivy(常春藤), can climb walls using sticky pads. The pads help ivy stick to wood, stone, and other surfaces. After studying this plant, scientists created soft climbing robots. Though small, these robots are strong enough to move on different surfaces and turn corners. This allows them to work in hard-to-reach places.
Another amazing plant is the exploding cucumber(喷瓜). It has a cool trick. When touched, it shoots seeds up to 6 metres away. Learning from this plant’s “body language”, medical researchers have developed a new way to send medicine to where it’s needed in the body, just as the plants shoot seeds to the right places.
Plants may seem quiet and still, but their special movements have given ideas to real-world inventions. Next time you see a plant, watch its “body language” carefully; you might catch the next scientific breakthrough.

A. Under water. B. On the farm. C. On high walls. D. In playgrounds.
() 6. What is special about the exploding cucumber?
A. It can play tricks on others. B. It can send out the seeds far.
C. It helps people make medicine. D. It can grow up to 6 metres tall.
() 7. What is the best title for the passage?
A. Nature’s behaviour B. Plants have gone wild
C. Nature’s language D. Plants drive creations

答案
4. D 5. C 6. B 7. D
解析
4. 第二段介绍的SmartFlower太阳能板的特性为：外形为花形，白天有太阳时花瓣展开追光，天黑或者遇到暴雨等恶劣天气时花瓣会闭合。选项A（雨天花瓣展开）、B（夜晚花瓣展开）、C（晴天太阳下花瓣收拢闭合）均和原文描述不符，只有D（夜晚花瓣收拢闭合）符合该发明的特点。
5. 根据第三段内容，爬墙机器人是受常春藤依靠粘性吸盘爬墙的启发研发的，可以在不同表面移动、抵达难以到达的区域，因此它被设计用于高墙这类难以抵达的位置工作，其余选项场景均不符合原文说明。
6. 根据第四段原文"When touched, it shoots seeds up to 6 metres away."可知喷瓜的特殊之处是可以将种子喷射到很远的地方，其余选项的描述均和原文内容不符。
7. 全文围绕植物的特殊运动启发人类研发各类实用新发明展开，核心是说明植物推动了相关创造发明，其余选项都无法概括全文的核心内容。
